Threat detection and response capabilities enhance investigation processes
My security team has been using Microsoft Sentinel for around two years. We also have Bastion and SolarWinds as part of our monitoring tools. We use a three-way tool, alongside Microsoft Sentinel, in our environment The most valuable features for us include threat collection, threat detection,…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The features that stand out are the detection engine and its integration with multiple data sources."
"There are a lot of things you can explore as a user. You can even go and actively hunt for threats. You can go on the offensive rather than on the defensive."
"Mainly, this is a cloud-native product. So, there are zero concerns about managing the whole infrastructure on-premises."
"You can fine-tune the SOAR and you'll be charged only when your playbooks are triggered. That is the beauty of the solution because the SOAR is the costliest component in the market today... but with Sentinel it is upside-down: the SOAR is the lowest-hanging fruit. It's the least costly and it delivers more value to the customer."
"Microsoft Sentinel enables you to ingest data from the entire ecosystem and that connection of data helps you to monitor critical resources and to know what's happening in the environment."
"Sentinel improved how we investigate incidents. We can create watchlists and update them to align with the latest threat intelligence. The information Microsoft provides enables us to understand thoroughly and improve as we go along. It allows us to provide monthly reports to our clients on their security posture."
"The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"The most valuable feature is the UEBA. It's very easy for a security operations analyst. It has a one-touch analysis where you can search for a particular entity, and you can get a complete overview of that entity or user."
"The security level that they are maintaining with the pre-authentication keys is very good."
 

Cons

"Microsoft should improve Sentinel, considering that from the legacy systems, it cannot collect logs."
"The troubleshooting has room for improvement."
"When it comes to ingesting Azure native log sources, some of the log sources are specific to the subscription, and it is not always very clear."
"The integration challenges arise from both sides; Google tends to be noisy, and we find only ten analytic rules out of the box, necessitating the use of Defender for Cloud for alerts, which indicates a need for better documentation during deployment."
"They should just add more and more out-of-the-box connectors. It is quite a new product, and it has a lot of connectors, and even more would be good."
"From a client perspective, they'd like to see more cost savings."
"They should integrate it with many other software-as-a-service providers and make connectors available so that you don't have to do any sort of log normalization."
"Given that I am in the small business space, I wish they would make it easier to operate Sentinel without being a Sentinel expert. Examples of things that could be easier are creating alerts and automations from scratch and designing workbooks."
"The solution could improve by providing better documentation for beginners to learn, such as videos or other tutorials."
 

Pricing and Cost Advice

"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"Sentinel is a pay-as-you-go solution. To use it, you need a Log Analytics workspace. This is where the logs are stored and the cost of Log Analytics is based on gigabytes... On top of that, there is the cost of Sentinel, which is about €2 per gigabyte. If a customer has an M365 E5 license, the logs that come from Microsoft Defender are free."
"The solution is expensive and there is a daily usage fee."
"No license is required to make use of Sentinel, but you need to buy products to get the data. In general, the price of those products is comparable to similar products."
"The combination of the ease of accessibility and the free cost of the service is great. But we buy storage based on our events per second and on how many sources are integrated into the solution."
"From a cost perspective, Microsoft Sentinel is quite costly."
"It varies on a case-by-case basis. It is about $2,000 per month. The cost is very low in comparison to other SIEMs if you are already a Microsoft customer. If you are using the complete Microsoft stack, the cost reduces by almost 42% to 50%. Its cost depends on the number of logs and the type of subscription you have. You need to have an Azure subscription, and there are charges for log ingestion, and there are charges for the connectors."
"Microsoft Sentinel is included in our E5 license."
"The solution is not expensive for the data security measure you receive, it is reasonable."
